Ch0cu3r Posted November 5, 2013 Share Posted November 5, 2013 Have you fixed this? I do not get a 500 Error when I add/edit/delete records. When you get a 500 Internal Server Error check your servers error log to see why you are getting this error. Quote Link to comment Share on other sites More sharing options...
